Time for the whole journey;
Time=
![\frac{Distance}{Speed}](https://tex.z-dn.net/?f=%20%5Cfrac%7BDistance%7D%7BSpeed%7D%20)
t=
![\frac{440}{55} hours](https://tex.z-dn.net/?f=%20%5Cfrac%7B440%7D%7B55%7D%20hours)
t= 8 hrs
In driving 275 miles, you take,
t=Distance/speed
t=
![\frac{275}{55}](https://tex.z-dn.net/?f=%20%5Cfrac%7B275%7D%7B55%7D%20)
t= 5 hours
The remaining traveling time is;
8-5
= 3 hours
Answer:
1
Step-by-step explanation:
Answer:
w = - 16.06 or w = 2.06
Step-by-step explanation:
Given
w² + 14w - 33 = 0 ( add 33 to both sides )
w² + 14w = 33
To complete the square
add ( half the coefficient of the w- term )² to both sides
w² + 2(7)w + 49 = 33 + 49, that is
(w + 7)² = 82 ( take the square root of both sides )
w + 7 = ±
( subtract 7 from both sides )
w = - 7 ±
, that is
w = - 7 -
≈ - 16.06 or w = - 7 +
≈ 2.06
Answer:
Negative Correlation
Step-by-step explanation:
Since the points are approximately lined up in a linear line pointing toward the bottom right, the slope of the best fit line would be a negative value. So the scatter plot shows a negative correlation.
